A pack of 40 beautiful retina ready wallpapers for your iPad or another retina ready device. You can download the retina wallpapers and use them as background on any device though.
If you want at least a glimpse of the look and feel of the brand new iOS 7 which was released last week, you can help yourself with the wallpapers below. I took the originals (which you can find in this post) and cropped them a bit to be more suited for Windows or Android devices. The size is 1920×1440, so standrad ratio but it works well on widesreen devices also.
